39. Scydmanus graminicola, N. 



iS. gracilior ; loug. corp. ^ lin. Antennae art. 3 et 4, 6 et 7, 9 et 10 

 inter se subsequalibus, 5° adjacentibus paulo longiore, .3-7 sub- 

 cylindricis, 8 subgloboso, 9-10 fortiter globosis cum ll°clavam 

 formantibus. Palpi maxill. art. 3° inverte coiiico, 4° mediocri. 

 Mandibulse apiee arcuatte, medio acuminate l-dentatse, basin ver- 

 sus sensim dUatatce. Thorax obcouicus, basi depressus, 2-sinuatus 

 et 2-foveolatus, rectangulatus. Pedes tibiis elonyatis basi apiceque 

 arcuatis. 



Of the usual brown colour, legs aud antenuae lightei*, tarsi and 

 palpi very light ; femora nigrescent at the apex ; hairs of occiput 

 and thorax rather long, the former slightly narrowed behind ; the 

 head thus of a somewhat rhomboid form. Antennal club com- 

 posed of three joints, the first two of which are strongly globose, 

 the last being acuminated and slightly cut away on one side at 

 the apex. The mandibles are furnished with an acuminated tooth 

 at the middle, bent at the apex, and, what is rather uncommon 

 in this genus, gradually enlarged towards the base. The thorax 

 is obeonic, rather longer than broad. The elytra are somewhat 

 more extended than usual in this group; the rudimentary hu- 

 meral costse are rather ])rominent, they are separately rounded- 

 ofF at the apex. Tibia more or less elongated, slightly bent at 

 the base and apex, at the latter place subcylindric and hairy. 

 Tarsi with joints 2-3 subequal, first pair slightly contracted. 

 A sexual distinction appears to be expressed in the length of the 

 tibiae, which are less elongated in certain individuals, which are 

 at the same time less robust than the others. The insect is 

 easily distinguished by its general appearance. 



40. Scydmcpiius pyrifonnit!, N. 



S. supra castanens, subtus brunneo-testaceus, pedibus antennisque 

 dilutioribus, tarsis palpisque fiavo-testaceis, anteunarum clava ni- 

 gricante. Long. corp. ^ liu. 



Antennae art. 3-8 fere subaequalibus, excepto H'^ parum longiore, 

 8° subgloboso, minore, 9-10 subglobosis majoribus cum 1 1° acuminate 

 clavam formantibus. Palpi maxill. art. 3° inverte conico, 4" minuto. 

 Thorax obovatus, basi 2-tbveolatus. Pedes coxis 2 posticis distan- 

 tioribus ; tibiis 2 auterioribus basi apiceque leviter arcuatis, reliquis 

 subsimplicibus ; tarsis art. 2-3 subajqualibus. 



A pretty little species, at once distinguished by its colour, 

 which is chestnut, darker at the base and suture of the elj-tra, 

 and light, more or less brownish or yellowish, below ; the an- 

 tennffi being of the latter colour, with a nigrescent club. The 

 occiput is slightly narrowed ; the head altogether ])lump, heavy, 

 and transverse. The antennal club is composed of three sub-
